Abstract: To address the external memory management issues in multiple virtual machine environment,the multiple virtual machine architecture is studied based on the virtual machine monitor.We sum up with the three main external memory management issues that virtual machine environment faced,namely,the isolation and protection of external memory space,the disributation of external memory space according to need and the expansion of it.Learning from the mature virtual memory management thought of operating system,we present a virtual external memory manager design,which effectively resolves the external memory management of the above problems.Experiments show that the virtual partition can be dynamically created and abolished,the capacity of virtual partition can be based on actual needs of dynamic growth and can achieve the partition-based write protection,the flexibility of external memory management greatly increased and the utilization of external memory space greatly improved.
